Key takeaways
  • With a spouse and one child, the spouse takes the marital property interest plus half of the residue.
  • With a spouse and two or more children, the spouse takes the marital property interest plus one-third of the residue, and the rest goes to the children.
  • Common-law partners have no intestate share, though a partner who meets the Family Law Act cohabitation or child test may be able to apply to the Court of King's Bench for support within four months of the death.

When a married person dies without a will, the law sets out who gets what. If there is a surviving spouse and children, the estate is shared between them under the Devolution of Estates Act. The split depends mainly on how many children there are.

This article walks through the rules and uses worked examples so you can see how the numbers fall out. Each family is different, so use this as a general guide and confirm the details with a lawyer.

This article covers the law of New Brunswick.

Two pieces: marital property and the residue

The rules divide the estate into two parts. First, the spouse takes the intestate's interest in marital property of the intestate and spouse. Second, the remaining estate, called the residue, is divided between the spouse and the children. The residue is, in plain words, what is left after debts, taxes and costs are paid. Funeral expenses, probate tax and fees, legal costs and similar items are paid from estate assets in a set order.

How the split works

FamilySpouse takesChildren take
Spouse and one childMarital property interest plus one-half of the residueThe other half of the residue
Spouse and two or more childrenMarital property interest plus one-third of the residueThe balance, divided per stirpes

Per stirpes means each child's share is divided by branch of the family, so if a child has died leaving children, those grandchildren share their parent's portion. The balance goes to the issue per stirpes.

Worked examples

Example one: a residue of $300,000, a spouse and one child. The spouse receives $150,000 plus the interest in marital property, and the child receives the other $150,000.

Example two: a residue of $300,000, a spouse and three children. The spouse receives $100,000 plus the interest in marital property, and each child receives $66,667.

These examples show only the residue. The marital property interest is calculated separately, and it depends on what the couple owned and how. It is often where a lawyer's help is most useful.

Special cases that change the numbers

Other claims and next steps

Intestacy is not the only path. A surviving married spouse may apply to the Court to have marital property divided in equal shares as against the estate, within four months of death, with an extension in limited cases. A spouse or child can also apply under the Provision for Dependants Act for maintenance and support if their resources are insufficient, generally within four months of death.

Going to the Probate Court is not strictly mandatory in New Brunswick, but it is recommended, especially when the estate includes real property. Where it is used, Letters of Administration appoint an administrator to collect assets, pay debts and taxes, and distribute to those legally entitled. The Court may grant administration to the spouse, next-of-kin or next-of-kin's spouse as it considers proper. The application goes to the probate office for the district where the deceased lived or held property. Before letters issue, a sworn statement of the estate's total value must be filed.

Frequently asked questions

Does the spouse get everything if the children are adults?

No. If there is a spouse and children, the spouse takes the marital property interest plus a share of the residue and the children take the rest. How this applies to your family depends on your situation, so it is worth confirming with a lawyer.

What if we were common-law and not married?

The intestacy provisions do not give an unmarried partner a share. A common-law partner may still apply for support as a dependant within four months of the death if they meet the Family Law Act test.

Who runs the estate when there is no will?

The Probate Court appoints an administrator by granting Letters of Administration, usually a family member or close friend. The Court may grant it to the spouse, next-of-kin or the next-of-kin's spouse as it considers proper.

What happens if one of the children has died?

If that child left issue alive at the intestate's death, the spouse's share is computed as if the child were living. Grandchildren take as issue per stirpes.
